My invention relates to the class of devices employed for polishingindefinite lengths of wire or rods and as more commonly employed inconnection with machines for straightening wire or rods, and an objectof my invention, among others, is the production of a polishing devicethatshall be simple in con-.

struction and particularly efficient in opera.-

section.

One form of device embodying my invention and in the construction anduse of which the objects herein set out, as well as others,

construction of the polishing units, together with the means forcontaining the same.

As has heretofore been stated thls dev ce is particularly of advantagewhenused for polishin in connection with wire stralghten ingmacliines,but only so much of the structure is shown herem as Wlll be necessaryfor an understandmg of the invention, m'the v drawings the numeralindicating a bracket arranged for support upon the bed of a machine andsecured thereto in any ordinary manner. This bracket comprises a bearing6 of any desired construction at its upper end to receive and supportfor'rotation a bearingsleeve 7 which, in the structure hereinshown, ismounted on ball bearings 8 coated in recesses in the bearing 6 and heldtherein as by means of plates 9 secured as by means of screws and asshown in Figure 3 of the drawings. Said bearing sleeve 7 extends throughthe plates 9 and ball bearings and has a pulley 10 secured thereto atits outer end as a means for rotating it.

The projecting end of said bearing sleeve opposite the pulleyv 10constitutes a pohsher support 11 and a bolster 12, sa1d support beingreduced in size as compared with sa1d bolster and'having openings 14 forpolishing units now to be described. The openings 14 extend from'theouter surface ofthe reduced end to a hole 16 extending axially throughthe sleeve and a shelf 17 is formed at eachend of each opening 14 ashort distance from the mouth of the opening a The polishing-units eachincludes a holder formed-to fit one of the openings 14, each holderhavingrlips 18'atopposite ends to be seated upon'the shelves17., Eachunit has a recess 19 for a polishing block 20 comprising a portion ofthe unit and made of any suitable abrading materialand of a size to Ifit tightly within said recess v The holders 15jareeach of a thicknessslightly less than the depth of the, opening 14 in which the unit islocated and they arefitted loosely enough in said openings to have aslight play-therein; Spring recesses 21 are'formed in'the ends oieachholder 15' to receivesprings 22, which springs may, if

desired, .beprovided with covers 28. A cover sleeve 24 is fitteduponthe-support 11, as shown in Figures 3 and 4,4,the structure s. hereindescribed providing a spacebetween the outer sides of the holders andthe inner surface ofthe cover sleeveto provide some radialplay of theholders to enable "ready insertion of a wire or rod 25 that is movedthrough the device, usually by suitable-feed rollsin connection with astraightening arbor, when such is employed. A slot'26 is formed throughthe sleeve 24for' the inscrtion of the units, the sleeve beingrotatableto locate said slot over any of the openings 14. and the sleeve maybesecured iniany suit- .ablemanner asby aiscrew'27. ,A hole 28 may beformed througheach holder into the rel r cesses l9ifor the insertion ofa tool when quired for removal of any of the blocks 20. The shelves 17form stops to limit inward movement of the polishing units.

In accordance with the provisions of the patent statutes I havedescribedthe p'rinci tion may be carried out by other means and applied to usesother than those above set out.

I claim 7 1. A polisher including a support comprising a rotatablymounted shank and a reduced end with a hole extending axiallytherethrough, said reduced end having oppositely arranged radialopenings with sh'oulders therein, polishing units loosely fitting insaid openings, said units including holders having lips to touch saidshoulders, each unit also including a polishing block locatedin a recessin each oi said holders, and a sleeve fitting said reduced end to retainsaid units in place.

2. A polisher including a support 00111- pri'sing a rotatably mountedshank an'da reduced end with a hole extending axially therethrough, saidreduced end having oppositely arranged radial openings, polishing unit-slocated in said openings, each unit in cluding a holder and a polishingblock located in a recess in said holder, a sleeve removabl'y fittingsaid reduced end and having a slot to register with each of said radialopenings for insertion of saidunit-s through said slot, and means forholding said sleeve in place. 7

3. A polisher including a support comprising a rotatably mounted shankand a reduced end with a hole extending axially therethrough, saidreduced end having oppositely arranged radial openings, polishing unitsloosely fitting said openings, saidunits including holders having springrecessesand a polishing block located in each of said recesses, springslocated in said spring recesses, and a sleeve inclosing said openings toretain said units in place and to receive the thrust of said-springs.

4. A polisher including a support rotat-' i ably mounted With aprojecting end and a hole extending axially therethrou'gh, saidprojecting end having oppositely arranged radial openings with shoulderstherein, polishing units loosely fitted in said openings and projectingtherethrough into said hole, each unit including a holder having lips toengage said shoulders to prevent outward radial movement of the unit,and each unit also including a polishing block'located in a recess ineach of the holders. 7 A
